Patent EP-0001078-A1 (EP)
Inventor: REBSDAT SIEGFRIED DR
IPC: C07D301/10
Filed: 1978-08-28
Abstract: Zur Herstellung von Äthylenoxid durch Oxidation von Äthylen mit Sauerstoff oder Luft werden Silber - Trägerkatalysatoren eingesetzt, die eine möglichst hohe Wirksamkeit besitzen sollten. Es wird ein Verfahren zur Verbesserung der Wirksamkeit von bereits eingesetzten Silber - Trägerkatalysatoren beschrieben, bei dem man den gebrauchten Katalysator zunächst mit einer inerten Flüssigkeit wäscht und anschliessend auf den gewaschenen Katalysator 1 bis 1000 Teile je 1 Million Teile Katalysator Cäsium, Rubidium oder eine Mischung davon aufbringt. Das Aufbringen erfolgt in der Regel mit Hilfe einer Imprägnierlösung, die Cäsium- und/oder Rubidiumverbindungen in Geeigneter Menge enthält. Mit diesem Verfahren gelingt es, Silber-Trägerkatalysatoren, die bereits für die Oxidation von Äthylen mit Sauerstoff oder Luft in Gebrauch waren, in ihrer Wirksamkeit erheblich zu verbessern.

Abstract: Die Erfindung bezieht sich auf einen Feldeffekttransistor für höhere Sperrspannungen. Bisherige FET für höhere Sperrspannungen mußten, um Lawinendurchbruch im stromführenden Kanal zu verhindern, mit einem oder mehreren in unterschiedlichem Abstand zum Kanal angeordneten Hilfselektroden versehen sein. Die Erfindung vermeidet diesen Nachteil dadurch, daß die zwischen Steuerelektrode (9) und Senke (5) liegende Driftstrecke (8) zur Senke (5) hin eine zunehmende Anzahl von Dotierstoffatomen enthält. Dies kann durch trichterförmige Erweiterung des Kanals oder der Steuerelektrode (9) oder durch zunehmende Dotierungskonzentration zur Senke (5) hin erreicht werden. Der erfindungsgemäße FET ist einfach integrierbar und zum Beispiel für Flüssgkristall-Display-Ansteuerungen verwendbar.

Abstract: An alarm system uses piezo electric crystals (2) which when vibrated produce an electrical signal that can be amplified and used to generate an alarm or perform some other action. Each crystal and amplifier (3) are in a sensor unit (1) with a latch circuit (7) and indicator (9). Vibrations latch the indicator on, and the signal is also passed to a central control unit (15). This responds with an alarm or other action, relay (25) controlled, and an energised indicator (24). The control unit also has a re-set facility (20) and an indicator (22) for showing that the system is active. If the cable connection between any sensor unit and the control unit is cut, the effect at the control unit is that of a disturbed sensor unit.

Abstract: 1.

Abstract: 57 Apparatus (26, 72) in which lateral movement of a travelling belt (10) is controlled so that the belt (10) moves in a pre- determined path. The apparatus includes at least one roller (22) having a plurality of spaced-apart resilient fins (72) extending outwardly from the exterior surface thereof. The portion of the fins (72) contacting the belt (10) passing thereover provides support therefor. Preventing the belt (10) from deviating laterally from the pre-determined path by more than a chosen extent deflects the portion (72a) of the fins (72) in contact with the belt (10). The deflected portions (72a) of the fins (72) return to their normal positions after coming out of contact with the belt. In this manner, the maximum lateral force applied to the edge of the belt (10) by deflection limiting means (26) never exceeds the minimum force required to buckle the belt (10).

Abstract: Bearing cups manufactured by deep-drawing and heat-treating sheet or strip steel having a higher carbon content have good strength but the deep-drawing step is difficult to carry out. If a low carbon content steel is used, the deep-drawing becomes easier but the heat-treating step does not produce a product having a satisfactorily high core strength. 
     The product is improved by using a sheet or strip steel consisting of iron, carbon, boron, manganese, silicon, aluminium and titanium. The utilization of a low carbon content steel containing boron produces bearing cups having good strength after the heat treatment step. The utilization of a higher carbon content steel containing boron produces bearing cups having strengths superior to those made from corresponding steels not containing boron and without increased manufacturing difficulties.

Les surfaces du materiau brut (20, 120) sont enrobees sur trois cotes avec un agent isolant et sur le cote a exposer avec un agent de lustrage ou bien laissees sans revetement. La chambre de cuisson (32) du four possede des rangees opposees de bruleurs (40) diriges vers des orifices opposes (42). Les rouleaux (35, 135, 36, 136) font saillie au travers de parois laterales et sont supportes sur des roues espacees circonferentiellement (70a, 70b, 70c). Les roues (73a, 73b) synchronisent les rouleaux. Un collecteur (56) connecte la chambre de cuisson (32) avec la chambre de prechauffage (30). Le procede utilise un melange d'une petite quantite d'un materiau carbone soluble et de l'eau avec soit une charge d'argile soit une charge de silice pour regler la composition. L'argile peut etre extrudee sous forme de ruban revetu avec l'agent isolant et l'agent de lustrage, puis mis a feu, prechauffe, au-dessus de 20000 F, et recuit. Les produits en argile vitreux cellulaires sont alors decoupes. Une charge de silice avec une surface de sable de silice peut etre comprimee avec un materiau pour former des plaques, puis cuite dans le four pour former un produit vitreux cellulaire. Des plateaux consommables, en section, sont egalement decrits.

Abstract: Disclosed is a self-aligned process for providing an improved high-performance bipolar transistor. The transistor device region is isolated from the other devices on the wafer by a wide deep oxide trench (16). The deep oxide trench which has nearly vertical sidewalls, extends from the epitaxial silicon surface through the N *  subcollector region into the P-substrate. A shallow oxide trench is used to separate the collector reach through region from the base region. A heavily doped polysilicon layer is used to dope and make contact to the transistor base as well as define the emitter window (28) through which the emitter is doped. In the structure, the separation between the emitter contact and the polysilicon base contact is reduced to a very small value. This is achieved by employing the self-aligned process in accordance with the invention. Metal contact to the polysilicon base contact is done over the deep trench oxide isolation. This allows the transistor base area, and hence the collector base capacitance to be minimized. The shallow emitter and narrow base width of the transistor are formed by ion implantations.
